SquirrelFish Extreme: Fastest JavaScript Engine Yet

The WebKit's newest JavaScript engine SquirrelFish Extreme is available now. This claims to be twice as fast as its predecessor (i.e. SquirrelFish), 35% faster than Google Chrome's V8 and 55% faster than Mozilla's TraceMonkey.

The following comparison chart shows how good the SFX engine is.


SFX uses four different technologies to deliver much better performance than the original SquirrelFish:
1. Bytecode optimizations

2. Polymorphic inline caching

3. Context threaded JIT compiler

4. Regular expression JIT compiler

This blog post on WebKit website explains these technologies in detail.
